MacOS 10.12, Vienna 3.1.6 RD 2. When I select (left-click) a headline, the right pane shows the detail text of that headline. But then if I right-click on a different headline, the headline shows that it is selected and the list of options appears, but if I don't select any option and then just left-click on that headline, the headline shows that it is selected, but the content in the right pane doesn't match the headline (it stays the same as from the originally selected headline).
